The new development snapshot has reached version 17.10 Beta 1, and provides mostly a preview of the upcoming operating system to Ubuntu testers.
This release as the first beta is of course not recommended for use in production systems.
"The first step of Artful Aardvark (to take place on 17.10) has been released! ISO images are available for Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio and Xubuntu. Recommended for Ubuntu flavor developers but also for those who want to help test, report and fix bugs, this version is ready. ”
